You need to use substitution, to do so, you isolate one of the variables x or y in one equation, and then you substitute that equation into the other.
Since you only need to find x, isolate the y in one of the equations
x - 2y = 4
y = 
Plug this in and simplify
9x + 2y = 16
9x + 2(
) = 16 Distribute the 2
9x + x - 4 = 16
10x = 20
x = 2 Your answer is C

Answer:
There are 659 blocks
Step-by-step explanation:
The number of blocks has 9 in the ones place.
The number in the hundreds place is one more that the number in the tens place.
Let the number in the tens place is x.
Number in the hundreds place = 1+x
These two numbers equal 11.
ATQ,
x+1+x = 11
2x + 1 = 11
2x = 10
x = 5
No in the tens place = 5
No. in the hundreds place = 1+5 = 6
Hebnce, the number is 659.
